| Outline of Research at the Start |
Sugars are abundant in nature and are structural diversity and high density of functional groups. This research aim to develop an effective heterogeneous catalytic system for transformation of sugars to corresponding valuable chiral products with retention of their original stereostructure.

| Outline of Annual Research Achievements |
Erythritol is a typical C4 sugar alcohol, and it can be an important building block in biomass refinery because of a possibility of its production by fermentation of glycerol, as well as glucose. Recently, erythritol was selected as the substrate for the deoxydehydration and hydrogenation (DODH + HG) over CeO2 supported Re catalsyt, and the kinetic modelling had been conducted. During the reaction, DODH + HG of primary-secondary vicinal OH groups in erythritol gives 1,2-butanediol while the consecutive DODH + HG of 1,2-butanediol results in n-butane. Contrary to it DODH+HG of 1,4-butanediol, formed as a product DODH + HG of the secondary-secondary vicinal OH groups in erythritol, does not proceed further. Moreover, it is envisaged that in the modelling of DODH + HG of erythritol will be connected to the prediction and the interpretation of the product distribution in DODH+HG of more complex sugars, i.e. xylitol and sorbitol.
